IIENRY n. GORTER, OF SAN ERANoisoo, CALIFORNIA, ASSIGNOR TO MARY E.scams,

MQVABLE WATER- F SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 637,507, dated November21, 1892.

Application filed March 16, 1899 To ctZZ whom it may concern.-

Be it known that I, HENRY H. GORTER, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invent-ed certain new and useful Improvements inMovable Water- Pipe Connections, of which the following is aspecification.

the joint.

For the purpose of illustration I have shown myinvention as applied to aportable fire-e tinguishing apparatus,although it may also be employedwith any other apparatus of which movable Water-pipe connections form apart.

In the accompanying drawings, Figure 1 is a side elevation of afire-extinguishing apparatus provided with my improvements.

Fig.

2 is a similar view, on an enlarged scale, of the portion of theapparatus to which my invention is more particularly applied; and Fig. 3is a section of a portion of a pipe-coupling of the fire-extinguishingapparatus to which my invention has been applied.

Referring to the drawings, 1 represents the frame of a portablewater-battery, mounted on wheels2 and having the shafts 3. In an openingin the frame is provided a platform 4, car- 'ried by pivoted links 5 onthe frame 3, and on said platform is mounted a siamesing-pipe 6,supplied from beneath the platform 1 by This construction of battery is16 of said frame.

The horizontal rotation of Serial No. 709,294, (No modeld the pipe 8 inthe pipe 6 is controlled by a ver tical shaft 17, working in bearings 18on the frame 13 and carrying a pinion 19, meshing with a gear-wheel 20,carried by the pipe 6. Suitable packing is interposed between the pipes(3 and 8 and also between the globularend 10 and the nozzle 11. Thisconstruc tion of nozzle is the same as that of my Patent No. 557,799, ofApril '7, 1896, and is disclosed more in detail therein.

Upon the platform a are secured storage batteries 21, and wires 22 leadtherefrom to a curren t-controller 23 and thence to electric heaters24,surrounding the pivotal connection of the pipes 6 and 8 and thepivotal connection of the end 10 and the nozzle 11. Each heater isformed of a large number of turns of a fine wire of German silver or asimilar high-resistance metal, and the wires of the heater areelectrically separated from the metal pipe 6 by one or more sheets ofmica 25 and are inclosed and protected from loss of heat by radiation bymeans of an asbestos covering.

In operation when in extremelycold weather the battery is brought out tobe used at a fire the current from the storage batteries is immediatelyturned on, and the heat generated by the passage of said current throughthe high-resistance wires warms the movable water-pipe joints inclosedby the heaters, so that said joints are not liable to be renderedinoperative by the freezing of the stagnant water therein.

I claim- 1. The combination of an outer pipe-section, an inner sectionmovable therein, insulating material surrounding the outer section, ahigh-resistance wire surrounding the insulating material, and means forsupplying an electric current to said wire, substantially as described.

2. The combination-of an outer pipe-section, an inner section movabletherein, insulating material surrounding the outersection, ahigh-resistance wire surrounding the insulating materiahmaterialsurrounding the wire adapted to prevent radiation of heat therefrom, andmeans for supplying an electric current to said wire, substantially asdescribed.

3. The combination of a truck or carriage, a pipe extending upwardlytherefrom, means for forcing water under pressure through said pipe, apipe-section movably carried on the upper end of said pipe, apipe-coupling con necting said pipe and pipe-section, a high-re sistaneeWire surrounding said pipe-coupling, insulating material between saidwire and coupling, a non-conductor of heat on the opposite side of saidwire to the insulating material, means carried by said truck or carriagefor supplying an electric current, wires there from to thehigh-resistance wire, and a current-controller on the truck,substantially as described.

In witness whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

HENRY H. GORTER.
